Development architectures translate the system’s compliance requirements into a concrete technical design. This section covers 50 articles across four subsections: the statement of business intent, the eight-layer reference architecture, infrastructure design, and the artefacts produced.

The statement of business intent establishes the system’s purpose, prohibited outcomes, ethical framework, and transparency commitments before any architectural work begins. The eight-layer reference architecture provides per-layer controls spanning data ingestion, feature engineering, model inference, post-processing, explainability, human oversight, logging, and monitoring. Infrastructure design addresses deployment topology, containerisation, and data sovereignty. The artefacts subsection documents the deliverables.

Note:

This section corresponds to the Development Architectures section and feeds primarily into AISDP Module 3 (Architecture and Design).
